Definitions

  • the present invention relates to control lever devices for vehicles, particularly a lever device for motorcycles in which the rest position of the lever can be adjusted.
  • the brake and clutch are manually actuated by means of a lever device that is mounted on the handlebar of the motorcycle, a hydraulic tube or a Bowden cable extending therefrom to the system to be controlled, such as a brake or a clutch.
  • the lever of the lever device is usually arranged on the grip of the handlebar and the motorcyclist, in order to actuate the lever, grips the handlebar together with the lever and clenches the hand such as to rotate the lever towards the grip.
  • the movement of the lever produces a thrust force acting on the hydraulic piston, the stroke or position thereof defining the fluid pressure inside said hydraulic pipe for the control of the brake or clutch.
  • Upon actuation by means of a Bowden cable the movement of the lever produces a traction force acting on the cable controlling the brake or clutch.
  • a number of various solutions have been suggested to provide an adjustment of the position of the lever.
  • a group of these solutions provides an adjustment screw being screwed in a suitable threaded hole of the lever such that an end portion of the shank of the adjusting screw projects from the lever hole and abuts against a seat of the support structure of the lever device or against a transmission portion being interposed between the lever and the piston to be actuated.
  • the length of its projecting portion, and hence the distance between the lever and said seat against which the adjusting screw abuts, can be changed.
  • adjusting screw In order to prevent that the adjusting screw may be accidentally and unvoluntarily rotated, for example both because of the vibrations of the motorcycle and a repeated actuation of the lever, it is known to provide locking devices for the screw, such as a nut or a ring nut being screwed on the adjusting screw and tightenable against the lever such that the threading of the adjusting screw is axially preloaded against that of the lever hole in order to increase the friction and accordingly the resistance against loosening of the screw.
  • locking devices for the screw such as a nut or a ring nut being screwed on the adjusting screw and tightenable against the lever such that the threading of the adjusting screw is axially preloaded against that of the lever hole in order to increase the friction and accordingly the resistance against loosening of the screw.
  • the ring nut requires that a tool (nut wrench) be used for loosening and tightening the ring nut whenever the position of the lever requires to be adjusted.
  • a further solution envisaged by the inventor of the present invention provides an elastic plate placed between the head of the adjusting screw and the lever in order to provide either an elastic or snap locking of the adjusting screw in the selected position.
  • the object of the present invention is therefore to provide an adjusting screw for control lever devices with adjusting lever having such characteristics as to overcome the drawbacks mentioned with reference to prior art as well as facilitating the assembly and maintenance of the adjusting screw.
  • an adjusting screw for a control lever device for vehicles in which said adjusting screw comprises:
  • the object of the present invention is further achieved by means of a control lever device according to claim 12 .
  • FIG. 1 is a perspective view of an embodiment of the device according to the invention.
  • FIGS. 2 to 5 are sectional views of several details of the device from FIG. 2 ;
  • FIGS. 6 and 7 are views of several details of the device from FIG. 2 .
  • a control lever device is generally designated with 1.
  • the device 1 comprises a support structure 2 with means for connecting the device 1 to a handlebar, for example one or more tightening portions 3 provided with suitable holes 4 that are optionally threaded to house clamping screws.
  • a cylinder-piston unit for example a cylindrical housing 5 directly made in the support structure 2 that slidingly houses a piston 6 .
  • a lever 7 is pivotally connected to the support structure 2 along an angular actuation stroke A extending from an angular rest position R of lever 7 in a first direction of rotation and along an angular collapse stroke C extending from said angular rest portion R in a second direction of rotation opposite to the first direction of rotation.
  • a transmission portion 8 is associated to the device 1 such that the movement of lever 7 is transmitted along the angular actuation stroke A to the cylinder-piston unit, particularly to piston 6 .
  • the transmission portion 8 is arranged relative to lever 7 such that, when the lever 7 is in the angular collapse stroke C, it is separated from the transmission portion 8 .
  • the lever 7 When the lever 7 is in the angular actuation stroke A, it rests against the transmission portion 8 such as to permit the transmission of the movement of the lever 7 to the cylinder-piston unit, particularly piston 6 , in order to actuate the brake or the clutch.
  • the adjusting screw that will be described below can also be used with conventional non-collapsible levers.
  • the transmission portion 8 is made, for example, as an elongated prop having a preferably round cross-sectional shape.
  • the prop has a first end 9 being permanently held in contact with a seat 12 of piston 6 and a second free end 10 suitable to abut against a suitable seat 11 of lever 7 , when the latter is in the rest position R and/or in the angular actuation stroke A.
  • the seat 11 is directly formed on an adjusting screw that will be described below.
  • the transmission portion 8 comprises, in an intermediate area between the first end 9 and the second end 10 , a connecting portion 13 for the connection of the transmission portion 8 to an elastic gasket 14 being provided for protecting the cylinder-piston unit from the external environment.
  • the gasket 14 holds the transmission portion 8 , i.e. the prop, elastically in a preset position at least when the lever 7 is in the angular collapse stroke C.
  • a threaded hole 16 to house an adjusting screw 15 suitable to act upon lever 7 such that the rest position R of lever 7 relative to the support structure 2 can be adjusted by rotating the adjusting screw 15 .
  • the threaded hole 16 is formed in the lever 7 in such a position that the adjusting screw 15 can rest by means of said seat 11 against the free end 10 of the transmission portion 8 for the movement of lever 7 to be transmitted to the transmission portion 8 and therefrom to the piston 6 .
  • the adjusting screw 15 comprises a screw body 18 with a threaded shank 19 that can be screwed in the threaded hole 16 of the lever device 1 as well as a locking body pivotally connected to the screw body 18 .
  • the locking body comprises, in turn, contact means interacting with the screw body 18 such as to counteract the rotation of the locking body relative to the screw body 18 to a certain extent.
  • the locking body further comprises anchoring means suitable to engage an anchoring seat 17 of the lever device 1 such as to prevent that the locking body may rotate relative to the threaded hole 16 .
  • the adjusting screw 15 comprises means for preventing that the locking body may be displaced along the shank 19 of the screw body 18 , independently of the position of the adjusting screw 15 inside the threaded hole 16 , such that the engagement of the contact means against the screw body remains constant despite the axial displacements of the adjusting screw.
  • the screw body 18 further comprises a actuating head 20 that is rotatably integrally connected (preferably in a removable manner) to a first end 21 of shank 19 to allow the shank 19 to be screwed inside the threaded hole 16 by means of the manual rotation of the actuating head 20 .
  • the first end 21 of shank 19 has a front surface 22 from which there protrudes an elongated portion 23 for connecting the shank 19 to the actuating head 20 .
  • the elongated portion 23 protrudes from an intermediate portion having a greater diameter than the diameter of the elongated portion, though being smaller than that of the remaining part of the shank 19 .
  • the front surface 22 , a part of the elongated portion 23 , i.e. the intermediate portion, and a contact surface 24 of the actuating head define a substantially annular seat 25 to house the locking body such as to prevent that it may be displaced along the shank 19 .
  • the locking body is advantageously embodied by a substantially annular elastic plate 26 extending about the shank 19 of the screw body 18 (particularly about the elongated portion 23 or the intermediate portion), where it is housed in the annular seat 25 .
  • the elastic plate 26 has one or more shrinkable projections 27 suitable to snap engage at least one cavity 28 being generally formed in the screw body 18 such as to provide said contact means.
  • the cavities 28 are formed in the contact surface 24 of the actuating head 20 .
  • the intermediate portion of the elongated portion 23 advantageously provides a stop surface for the actuating head 20 such that the axial length of the intermediate portion defines the relative position between the locking body, i.e. the elastic plate 26 , and the contact surface 24 of the actuating head 20 and hence the amount of elastic preload of the elastic plate 26 itself.
  • the contact means can be provided either as elastic friction means, snap elastic means, clamping friction means or threaded clamping means.
  • an anchoring tab 29 (for example shown in FIG. 4 ) in the longitudinal direction of shank 19 .
  • the anchoring tab 29 is suitable to rest against the anchoring seat 17 of lever 7 and can slide along this anchoring seat 17 to follow the stroke of shank 19 within the threaded hole 16 .
  • the anchoring seat 17 is preferably formed on the outer surface of lever 7 and substantially extends in the longitudinal direction of the threaded hole 16 to allow the displacement of anchoring tab 29 in said direction, while preventing that it may rotate together with the shank 19 of the adjusting screw 15 .
  • the seat 11 engaging the transmission portion 8 is directly formed at a second end 30 of the shank 19 that is placed opposite the actuating head 20 .
  • the seat 11 is funnel-shaped to facilitate the proper alignment of the adjusting screw with the transmission portion of the control lever device, particularly when the lever 7 enters from the angular collapse stroke C in the rest position R.
  • both the actuating head 20 and the seat 11 have a greater diameter than the diameter of the threaded shank, such that the adjusting screw 15 , when mounted, substantially cannot be lost.
  • the shank of the adjusting screw is screwed in the threaded hole of the lever to such an extent that the front surface of the shank emerges from the aperture of the threaded hole.
  • the annular elastic plate can be now fitted on the elongated connecting portion, by directing the annular elastic plate such that the anchoring tab is aligned with the anchoring seat of the lever.
  • the actuating head is fitted on the elongated connecting portion and joined thereto by means of either a shape or interference connection.
  • the annular elastic plate is now housed in the seat formed by the front surface of the shank and the contact surface of the actuating head which prevent it from being displaced along the shank of the adjusting screw.
  • the width of the annular seat, the height of the shrinking projections 27 of the elastic plate and the depth of cavities 28 of the actuating head define the elastic preload of the elastic plate and, accordingly, the strength of the same against a relative rotation between the screw body and the annular elastic plate, i.e. the lever 7 .
  • This strength remains constant independently of the adjusting position of the adjusting screw and is entirely insensitive to the vibrations of the motorcycle.
  • the surface of the lever or the support structure of the control lever device does not act as the friction surface to lock the adjusting screw. This facilitates the manufacture of an optional surface covering for example for the lever.
